ACETYLENE-GENERATING LAMP.

Specification of Letters Patent.

Patented March 26. 1907. i

' Application filed March 29.1905. Serial No. 252,758.

To all whom it may concern.-

Be it known that I, ERNST WACHTER, a citizen of the Swiss Republic, anda resident of Buchs, St. 'Gallen, Switzerland, have invented certain newand useful Improvements in Acetylene-Generating Lamps, of which thefollowing is a specification.

The subject of this invention is an acetylene-lamp which regulates thegeneration of gas automatically.

The accompanying drawing, wherein similar numerals refer to similarparts throughout the several views, shows in Figure 1 a longitudinalsection of the lamp; Fig. 2, a cross-section of the same.

The lam consists in the main of a casing 13, on the lbwer art of whichis provided a box 3 for the carbid, which box isheld by a frame 18, theparts of which are united by hinge-joints and communicates through atube 19 with a Water-reservoir 2: The bottom 20 of the casing 13 isplaced a little higher up into the inside of the same for the purpose ofobtaining a collecting-space 21, with which communicates a burner 4.

The carbid-receptacle 3 is, by a frame 18 with hinge-joints, pressedagainst a packing 22for instance, of indiarubberwhereby there iseffected a gas-tight connection with the collecting-space 21, which isseparated by a sieve-bottom 16 from the carbid-receptacle. In the bottom20 is arran ed an ascension-pipe 5, over which there is p aced acylinder 6 with a valve 11. This cylinder 6, which is placed inside of asecond cylinder 15, filled with water up to the inlet-tube 25 and passesthrough a guide-socket 26, is connected through a hook 7, s ring 8,levers 9 and 10 with a rod 1, at the lower end of which is provided avalve 1", which enters into the tube 19. The tube 19 is provided withholes, which can be closed or opened by said valve 1.

the reservoir 2 through the holes in the wall of the tube 19 and throughthis tube into the carbid-receptacle 3, Where a generation of acetylenetakes place. The gas generated in the box 3 enters through apurifying-sieve into a collecting-space 21, from which it passes to theburner 4 after being purifiedby a mixture of felt and salt and can herebe ignited. If more gas than required is generated and the flame burnsuniformly, the excess of pressure acts on the cylinder 6, whichcommunicates through an ascension-tube 5 with the collecting-space 21,raises the cylinder 6, which is connected by means of the hook 7, spring8, and levers 9 and 10 with the rod 1, and consequently, also, with thevalve 1, which latter can reduce or entirely stop the flow of water fromthe reservoir 2 into the box 3. If a very intense generation of gasshould take place and the piston 6 be in its highest position, itstrikes with a pin 12, fixed to a valve 11, against a casing 13 andopens the valve 11, through which the gas can now stream out, so that anexplosion is thus prevented. In order to stop the generation of gas, thelamp is provided with a screw 14, which presses, by means of a lever 10,on the valve 1 and can entirely stop the Water-suply to the box 3. Ifthe automatically-reguated device should fail to-act, an ex los1on canall the same be prevented, as the ox 3 is arranged on springs 17, whichyield to an overpressure of gas, and thus produce an opening between thecasing 13 and the box 3, through which the superfluous gas can streamout. If the carbid in the receptacle 3 is consumed, the receptacle canbe taken out after moving the hook 24 and turning down the frame 18 andbe replaced cle filled with carbid and which was kept ermeticallyclosed. The frame 18 is then turned up again and secured by the hook 24.This changing of the carbid-receptacle can be effected very rapidly, sothat the lighting will be interrupted for only a short time.

What I claim as my invention, and desire to secure by United StatesLetters Patent, 1s

An improved acetylene-lamp, comprising in combination with a casing 13with double bottom a frame 18, hingedly connected to the lower end ofsaid casing 13 a carbid-box 3, springs 17 supporting said box andarranged to press the same against the lower bottom of the said casing apacking 22 between the top edge of the carbi -box 3 and the lower bottomof said casing a hook 24 on said frame 18, a water-receptacle 2 withmeans for introducing water, rigidly connected with said by a sparereceptacylinder 6 a tube 5 extending from above the said carbid-boX 3into said cylinder 6 a water seal for said cylinder, means 14 for shut-1 ting off the water-supply to the carbid by I hand, a burner 4 fixed tothe said casing 13 between the two bottoms of the same and means forpurifying the gas substantially as described and shown and for thepurpose set forth.

In. testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
